The preferred'form 'ofeonstl uction, as

Said screen is supported by a ring 22 provided at its upper end which engages an annular seat'o'r' shoulder 23 pro'vi'dedflac'b jacent the upper edg'eof said bowl; Thearrangement is su'oh "that, said' 's'ore en is 'held concentric with the bowl 11 a fpa'ss'age'fi 9 beiiig formed between said screen and bowl whichlea'ds to an 'outlet openiii g 25.

The"brushes 20 are rigidly fastene d to to" constantever, that the members18"andf19 a-reoiaeihiitis effected through the medium of a sleeve 26 which is threaded upon the depend ng free end of bracket 15, said sleeve being formed with an annular outwardly project same and consequently to raise or lower the brushes 20.

Said hand wheel is locked in positions of rotary adjustment by means of a. latch 31 pivoted at 32 upon bracket 15, the free end of said latch being adapted to I engage with any one of a plurality of openspokes of said wheel.

jugs 33 formed in the such, as will be seen,

The arrangement is that the member 18 and flange 28 are free to of the sleeve 26 and the brushes be as readrotate independently flange 27, so that ad ustment of toward and from the screen may ily effected durin operation of the machine as when the same is stopped.

Vertical adjustment of the operative position of bracket 15 in order to obtain proper centering of shaft 16 is effected by means of a s-et screw 34L threaded in a cross piece at the upper end of frame 10, which set screw is adapted to contact with the underside of said bracket as clearly seen in Fig. 5. Outward and downward swinging o-f'bracket is limited by a lug 35 provided at the pivoted end thereof which is adapted to contact with the lower flanged edge of cross piece 10, as will be readily understood.

The material tobetreated, such as tomatoes, is introduced into themachine by clepositing the same into a hopper 36, supported by the bracket 17, said hopper being arranged to discharge into the upper end of hollow shaft 16, whence the material travels downwardly in said shaft and being deposited into the lower end of screen 21..

At this point the material is caught up by the brushes 20 and. forced thereby through the screen 21. Refuse, such as the hard green portions of tomatoes and mold and other undesirable parts thereof, are forced by said brushes upwardly into an annular passage 37, formed at the upper edge of bowl 11. The refuse collected in said passage is caught up by a sweep 38 carried by one of the brushes 20 and discharged thereby through,an opening 37 into a refuse discharge chute 39 which leads laterally from the machine. The material which is forced through the screen enters the passage or space 24 whence the same passes downwardly, being discharged through the outlet 25.

Driving of the shaft 16 is effected by means of a pulley 10 fixed to the upper end portion thereof. Provided upon bracket 15 are pulleys 41 arranged subsequently coplanar with the pulley with their axes ily repaired or replaced. Through the arms 13 which are provided at their outer ends with screws 44L adapted to engage against opposlte sldes of frame 10 when said bracket is in operative position, as clearly seen in Fig. 2. By adjusting the screws ate into engagement with frame 10 it is, of course, apparent that bracket 15 and hence shaft 16 will be securely held against lateral vibration, said screws, at the same transversely of the machine. The top of the bowl 11 is provided with a cover formed of two sections 4L5, adapted to be locked together by suitable fastenings l6 and to be fastened to the upper portion of by suitable fastenings 47.

A machine of the construction set forth is highly efficient and is not susceptible to readily becoming inoperative. The swinging mounting of the shaft-carrying bracket, permits of said shaft, together with the brushes and other parts carried thereby, being swung out of registration with the screen. The parts are thus rendered readily accessible, with the result that the machine maybe easily maintained in clean and sanitary condition and broken or dlsabled partsreadfastening of the brushes 20 to the supporting members 18 and 19, whereby said brushes are constantly held in parallel relation with the screen, said brushes wiear uniformly along all points thereof, with the result that the life of each brush 'isextended to the maximum which, of course, would not be the case was the wear on the brushes not uniform.

While I have illustrated and described one form of my invention it is, of course, apparent that changes and modifications may be made in this form without departure time, afl'ording means for accurately centering the shaft said bowl from my invention, the scope of which is defined by the claims hereunto appended.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
